Chapter 4 The Parallax Effect

Mira looked at Elias, and she saw the way the light from the observatory's single fluorescent tube fell across his face — the sharp line of his jaw, the dark eyes that were currently narrowed in what she had learned to recognize as concentration, the slight parting of his lips that suggested he was about to say something and was waiting for the right moment to say it. He was wearing a navy blue sweater that she had noticed in the hallway that morning, the one that made his hair look darker and his skin look lighter, and she had spent approximately forty-seven seconds staring at him before she had remembered that she was supposed to be looking at her laptop screen and not at the president of the astronomy club. Forty-seven seconds. She had counted them. She was not proud of this. "The telescope is showing a pattern," she said. "Not a constellation. Not anything natural. A pattern that repeats every 1,247 days, which is not a number that matches any known orbital period or precessional cycle." Elias stepped closer to the telescope, his eyes fixed on the digital display, and Mira watched him read the coordinates the way he read everything — carefully, precisely, with the kind of attention that suggested the numbers were not just information but meaning, that every digit carried significance that went beyond its numerical value. "1,247," he said. "What does that number mean?" "Nothing that I can find," Mira said. "I have checked against every database I have access to — NASA's orbital mechanics database, the International Astronomical Union's catalog, the European Southern Observatory's records. Nothing matches. It is a prime number, which is interesting because prime numbers do not tend to appear in natural orbital periods. They appear in human calculations, in codes, in things that are constructed rather than discovered." "Constructed," Elias repeated. "You think someone constructed this pattern." "I think the stars are not random. I think there is a principle behind their arrangement that we do not understand yet, and I think this pattern is a clue — a clue that someone, or something, wants us to find." Elias was silent for a long moment. He was looking at the display, but Mira had the impression that he was looking through the display, at something beyond it, at the sky itself, at the stars that were beginning to appear in the darkness beyond the observatory's open dome. The sky was a deep violet, the color of the space between stars, and the first lights were appearing — Vega, bright and blue, standing high in the eastern sky, and Deneb, and Altair, the three stars that formed the Summer Triangle, and beyond them, invisible to the naked eye but visible to the telescope, millions of other stars, each one a sun, each one a question, each one a possibility. "You have been doing this alone," he said. It was not a question. "For three weeks." "Why didn't you tell me?" Mira felt something tighten in her chest. It was not anger. It was not defensiveness. It was the feeling of being seen, of having your solitude observed and named by someone who had not earned the right to name it, and yet had done so anyway, with a simplicity of statement that was more devastating than any accusation. "Because you are the astronomy club president," she said. "And I am the physics Olympiad team member. And we are not the same kind of people. You look at the stars and see beauty. I look at the stars and see data. We do not —" She stopped herself. She had almost said the word we do not talk, and she was not sure she wanted him to know that she had been considering that possibility, that she had been considering the possibility of talking to him about the stars, about the patterns, about the impossible word that had appeared in the sky and that she had not yet told him about. "You do not what?" Elias asked. "We do not have anything in common," she said. "That is not true." "It is." "It is not." He stepped closer to her, close enough that she could smell the soap he used, something clean and simple that reminded her of the kind of soap her mother had used when she was a child, the kind that came in a bar and did not have a pump and did not cost more than three dollars at the grocery store. "You fixed the telescope. I could not fix the telescope. You found a pattern in the stars that I did not see. I could not see the pattern. You have been doing this work for three weeks, and I have been running meetings and taking attendance and pretending that being president of a club with three members is a fulfilling use of my time." Mira looked at him, and she saw something in his face that she had not expected. Not anger. Not frustration. Not even the determination she had come to expect from him, the quality that made him the kind of person who arrived at the observatory at 5:47 every Friday regardless of weather or schedule or the state of his personal life. It was something else. It was vulnerability, raw and unguarded, and it made her want to look away and not look away at the same time. "I did not know you were struggling," she said. "I did not know anyone would care if I told them." The fluorescent light hummed above them. The telescope sat between them, its tube pointing at the sky, its coordinates still displaying the impossible pattern, the pattern that repeated every 1,247 days and that led, Mira was beginning to suspect, to something neither of them had anticipated. "What if we work together?" she said. Elias blinked. "What?" "We work together. You have the telescope and the observatory and the membership list and the administrative authority. I have the data and the algorithms and the database access. Between us, we can decode whatever this is. And if we are right — if the stars are telling us something — then we need to understand it before someone else does." "Someone else?" "The administration. The school board. The state education department. Whoever controls the telescope controls the data, and the data is —" She stopped. She had almost said the word valuable, and she was not sure she wanted to use that word, because it made the stars sound like a resource rather than a mystery, and the mystery was the most important thing about them. "Before what?" Elias asked. "Before it is taken away," she said. "Before someone decides that the telescope is too expensive to maintain or that the data is too sensitive to share or that the pattern is too dangerous to investigate. We need to understand it now, while we have the chance." Elias was silent for a long moment. He was looking at her, and she could see the way his mind was working, the way he was calculating the probabilities and the risks and the outcomes, the way he was trying to determine whether trusting her was the rational choice or the emotional one. She had learned, over the school year, to read that expression, and she knew what it meant: he was deciding whether to let her in, whether to share the observatory, whether to allow himself the possibility of collaboration with someone who was not part of his world. "Okay," he said. "Okay?" "We work together. But there are rules." "Like what?" "One, you do not touch the telescope without my permission. Two, you do not share the data with anyone outside this room. Three —" He paused, and something shifted in his expression, something that made Mira's heart beat faster. "Three, you tell me when you have decoded the pattern. Not when you think you have decoded it. Not when you have a hypothesis. When you know. And when you tell me, you tell me everything." Mira nodded. "Deal." "Deal." He extended his hand, and she took it, and for a moment they stood there in the observatory, their hands clasped, the telescope between them, the stars above them, and Mira felt something she had not felt in a long time — the feeling of being on the edge of something, of standing at the threshold of a discovery that would change everything, and of knowing, with a certainty that had nothing to do with data and everything to do with instinct, that she was not standing there alone. ---
